Amiodarone therapy before heart transplantation as a predictor of thyroid dysfunction after transplantation.

Background: In recent years we have observed new cases of thyroid disease occurring after heart transplantation (HTx). In these patients, the presence of this disease complicates their post-transplant course and occasionally results in life-threatening thyrotoxicosis. The present study examines the incidence and risk factors of thyroid disease in these patients with special emphasis on the use of amiodarone before HTx.
